Disc and thin film dryers are applied for both, full and partial drying. Disc dryers consist of a cylinder with an internal hollow shaft fitted with welded-on discs. Sewage sludge is transported through the cylinder, while drying takes place by heat transfer through the discs. Heat transfer in thin-film dryers occurs via a double-walled …
The sludge is pumped into the dryer where the rotating blades on the rotor convey and evenly spread the sludge into a thin film (1-3mm) against the outer heating surface. Heating fluid (steam, water, or thermal oil) flows on the outside of the heating surface and heat is indirectly transferred to the sludge film.
Vacuum Disc Paddle Dryer has been increasingly used for drying various kinds of sludge due to low temperature drying, low energy consumption and zero emission working condition. WHAT YOU NEED TO KNOW ABOUT PREVENTION AND CONTROL OF NOVEL CORONAVIRUS DISEASE(COVID-19)
Disc dryers work according to the contact dryer principle. Designed for partial drying of dewatered sewage sludge, they are heated with saturated steam and used for medium to large sludge volumes.
Unique sludge thickener for efficient sludge treatment . For wastewater treatment plants up to 200,000 PE; The heart of the S-DISC sludge thickener is an inclined, slowly rotating filter disc that separates flocculated sludge from filtrate. A baffle plate distributes the inflow from the flocculation reactor evenly across the entire filter radius.
Paddle, disc and thin film dryers are examples of conductive dryers which apply heat indirectly to the sludge solids through coming into contact with a rotating heated surface. For a paddle dryer, heated horizontal paddles rotate in the sludge solids.
The dryer is based on the functional principle of contact drying via steam-heated discs and, compared to other drying processes, impresses with its compact design as well as several innovative features, functionalities and decisive advantages for reliable state-of-the-art drying of sewage sludge.
The disc sludge dryer consists of horizontal casing and a heating disc. Through the rotation of the disc, the material in the disc is heated evenly for drying and dehydration.
